Abstract: 1,016,298. Stereophonic pick-ups. NIPPON COLUMBIA KABUSHIKI KAISHA. June 27, 1963 [Aug. 2, 1962; May 1, 1963], No. 25629/63. Heading H4J. A sterophonic pick-up comprises two conductors supported parallel to one another each in a magnetic field and joined by a stylus carrier. The two conductors R 1 , R 2  (Fig. 2), are metal ribbons or wires. They are disposed in air gaps g 1 , g 2  respectively of a magnetic circuit comprising a permanent magnet 1 and a member 2 of " soft " magnetic material. The conductors R 1 , R 2  are held under tension by supports S 1 , S 1 <SP>1</SP> and S 2 , S 2 <SP>1</SP> (Fig. 1, not shown), at their ends. The supports S 1 , S 1 <SP>1</SP> and S 2 , S 2 1 are connected to terminals t 1 , t 1 <SP>1</SP> and t 2 , t 2 <SP>1</SP> respectively. In use the output from terminals t 1 , t 1 <SP>1</SP> corresponds to modulations of one groove wall of a 45/45 type record while the output from terminals t 2 , t 2 1 corresponds to modulations of the other groove wall. In another arrangement (Figs. 4 to 8, not shown), two parallel coils L 1 , L 2  are wound on a common bobbin 11 secured in non-magnetic housing. The portions L 10 , L 20  of the coils L 1 , L 2  are adjacent a groove 13 in the bobbin 11 and vibrate in the air gap provided by a permanent magnet 1 and polepieces in response to movement of a stylus 3c.

Abstract: 653,156. Vehicle suspensions. RELIANT ENGINEERING CO. (TAMWORTH), Ltd., ALLEN-BOWDEN, Ltd., and HOLISTER, F. D. Oct. 4, 1948, No. 25757. [Class 108(ii)] In a motor vehicle having a single front steerable wheel carried by a forwardly extending arm which is mounted on a horizontal pivot, the horizontal pivot consists of a tube which contains a torsion bar, one end of the bar being anchored and the other end projecting beyond the tube and being connected to the forwardly extending arm to provide a resilient suspension for the arm and wheel. Means for adjusting the torsion bar are provided. Fig. 1 shows the suspension device in plan. The steerable wheel (not shown), is mountel at the outer end of arm 11, the inner end of which is bolted to a forked member 17 whose two arms are articulated on the horizontal transverse tubular frame member 14, preferably by means of rubber bushes. A torsion bar 26 is disposed within the tube 14, its outer end projecting through the longitudinal frame member 16 and being rigidly connected by arm 27 to the wheel carrying arm 11.

Abstract: 1,057,821. Tunnel diode circuits. WESTERN ELECTRIC CO. Inc. June 28, 1963 [June 29, 1962], No. 25763/63. Heading H3T. A monostable circuit comprises a tunnel diode in parallel with the series combination of a backward diode and an inductance, the input being applied to the common like terminals of the two diodes. In Fig. 3 the tunnel diode 13<SP>1</SP> and backward diode 18 have characteristic curves which intersect at the peak of the tunnel diode curve, and the inductance is in the form of a shorted stub 17 for operation at 150 Mc/s. When a signal is applied from source 27, the operating point moves up to the peak of the tunnel diode curve and rapidly switches the backward diode 18 to its high resistance region. The energy stored in the inductance then drives the tunnel diode to its valley point and the circuit reverts to its former state. The output signal is passed through an isolating transistor 32 to a bi-stable circuit as in Specification 1,057,822 comprising a further tunnel diode 13, transistor 14 acting as charge-storage device, and negative feedback diode 15. If the transistor 14 is of silicon, source 37 and resistors 35, 36 are unnecessary, the latter being replaced by a direct connection.

Title: Production of aliphatic acids
Inventor: ELCE ALEC
IPC: A01G9/28
Filed: 1952-10-15
Abstract: Acetic acid and other aliphatic acids are obtained by oxidizing in the liquid phase at elevated temperature a paraffin of the formula C2H5.CH(CH3).R, where R is an alkyl group of at least two carbon atoms with a gas containing or consisting of molecular oxygen. Suitable paraffins include 3-methyl pentane, 2,3-dimethyl pentane, 3-methyl hexane and 3,4-dimethylhexane.  The paraffinic hydrocarbons employed may be in the form of the pure materials separately or in combination, or in the form of mixtures with hydrocarbons, paraffinic or otherwise, provided that the paraffinic hydrocarbons of the above formula constitute a substantial proportion of the mixture.  Inert diluents may also be present.  The oxidizing gas may be in the form of air or of mixtures poorer or richer in oxygen than is air. Part of the molecular oxygen may be in the form of ozone.  In order to maintain the reactants in the liquid phase the use of high pressures may be necessary.  Preferred oxidation temperatures are 130 DEG  to 200 DEG  C. and the process may be carried out batchwise or continuously.  The oxidation may be carried out in the presence or absence of an oxidation catalyst.  Suitable oxidation catalysts include the oil-soluble organic acid salts of manganese, cobalt, nickel, vanadium and copper, or the catalyst metal may be added in the form of an anion, whether as the free acid or a salt thereof, e.g. as a vanadate.  In examples: (1) a stainless steel reactor is charged with 3-methyl pentane containing manganese naphthenate and oxidation effected with air at 150-160 DEG  C. and 200 lbs. per square inch pressure.  The liquid products are circulated through a cooler and the lower aqueous acid layer is withdrawn as product and replaced with fresh 3-methylpentane to keep the total volume of liquid constant.  The oxidation is completed in batchwise manner and the product is distilled to recover first nonacidic material after which the lower aliphatic acids and water are distilled from the high boiling residues.  The mixture of wet acids is then dehydrated and distilled to yield acetic acid, together with some formic, propionic, and butyric acid.  If 2-methylpentane and normal hexane, respectively, are used instead of 3-methylpentane the yield of acetic acid is reduced in each case; (2) to (4) as in (1) except that the hydrocarbons used are 3-methyl hexane, 2,3-dimethyl pentane and 3,4-dimethyl hexane, respectively, and the oxidation temperature is 150-155 DEG C. Specification 743,989 is referred to.

Title: A process for the production of sulphuryl fluoride or sulphuryl chlorofluoride or both
IPC: C01B17/46
Filed: 1964-06-23
Abstract: SO2F2 and/or SO2ClF is produced by reacting HF with SO2Cl2 and/or SO2 and Cl2 at below 350 DEG  C. in the presence of a catalyst comprising a major proportion of active carbon and at least 5%, preferably 10-40% by weight of an alkali metal bifluoride.  Carbon of grain size 2-14 U.S. mesh and a bifluoride of Na, K, Li, Rb, or Cs may be used. These components may be associated in layers as a mechanical mixture, or the carbon may be impregnated with an aqueous solution of the bifluoride, then air dried and heated at above 100 DEG  C. in an inert gas, e.g. N2.  Alternatively, the bifluoride may be formed in situ from the fluoride and HF before reaction begins. To obtain mainly SO2F2, 1.05-1.5 moles SO2 and 2.05-3.0 moles HF per mole Cl2, and temperatures of 150-325 DEG  C., are used.  To obtain mainly SO2ClF, 1.05-1.5 moles each of SO2 and HF per mole Cl2, and temperatures of 100-250 DEG  C., are used. A pressure of 2-10 p.s.i.g. may be applied. The gas mixture is scrubbed with water to remove HF, HCl, SO2 and Cl2, passed through H2SO4 and alumina to remove water, and fractionally distilled to separate SO2F2 from SO2ClF.

Title: An apparatus for,and method of,analysis of liquids
Inventor: SHEEN ROBERT TILTON
IPC: G01N21/85
Filed: 1961-07-19
Abstract: Liquids, e.g. water supplies, are analysed for chemical constituents by introducing and passing the liquid through a reaction vessel, controlling the flow of the liquid through the reaction vessel at a constant rate, controllably feeding a liquid soluble continuous reagent filament into said reaction vessel in contact with the liquid therein, and determining the magnitude of a given property of the liquid after flowing through the reaction vessel.  The chlorine content of swimming pools or water supplies may be controlled by incorporating Chloramine T into the reagent filament and industrial waste coagulation can be controlled by incorporating alum.  The filament carrier consists principally of a polyvinyl alcohol, polyvinylpyrrolidone, dextran starch, carboxymethylcellulose, hydroxyethyl cellulose, polyethylene oxide or alginate.  The measurements are taken photo-electrically.ALSO:Molten aluminium is degassed by treating it with a filament of a plastic material, e.g. polyvinyl pyrrolidine, impregnated with hexachloroethane, thus avoiding contamination of the aluminium.
